Charles Stross' Laundry novels, at least, posit a connection between number-crunching and the occult, though unfortunately the series predates Bitcoin, which would have been perfect fodder.

In the TV show "Sherlock," the titular main character's self-deprecating videos for the "Everyone" collective (spoof on Anonymous) are a sort of ritual sacrifice as a medium of payment.

I think you're meaning to reference "Elementary," the other show about Sherlock Holmes.

Ah, you're absolutely right.
